MOUNTING FOR ENGINE ASGESSORIESS.

Application filed May 28, 1919.

T all whom it may concern Be it known that l, Annxnrrnnn GniswoLD Hnnnnsnorr, a citizen of the United States, residing in the borough of Manhattan of the city of New York, in the State of New York, have invented certain new and useful Improvements in Mountings for Engine Ac cessories, of which the following is a spoon fication, reference being had to the accon panying drawing, forming a part hereof.

This invention relates to a novel means for mountinghll of the accessories of an internal combustion engine in close proximity to one another and in a position which is most accessible for repairs or adjustments thereof. It has for one of its objects to eliminate much of the shafting which is now commonly employed in the actuation of such accessories and to provide a direct drive for the accessories from the crank shaft of the motor. It has for a further object in motor adapted for automobile use in. which the radiator is mounted at the rear of the hood to mount the accessories at the front end of the engine so that when the hood is raised the accessories will be accessible for demounting or inspection. Still another object of the invention is to provide a unitary support for all such accessories which may, in some embodiments of the invention, constitute a detachable section of the wall of the engine casing. Other advantages of the improved construction will appear as this description proceeds. In the drawing- Figure 1 is a view in front elevation of a mounting which comprises a plate adapted to form a detachable section of the engine wall.

Fig. 2 is a view in vertical section taken through the mounting shown in Fig. 1 alon the plane indicated by the line 22 of Fig. l and looking in the direction of the arrows, a portion of the engine casing being indicated.

Fig. 3 is a fragmentary detail view in plan of the improved mounting, one of the units being removed in the interest of clearness.

It will appear hereinafter that the inventive thought underlying the present invention resides in the bringing together of the accessories of an internal combustion engine and so mounting. them as to facilitate their assembling, disassembling and inspection While simplifying the operative Specification of Letters Patent.

driving connections for each such accessory unit. Accordingly, the invention is not to be limited necessarily to the precise embodiment illustrated h. sin, and it will be apparent that many or the advantages of the improved construction can be realized in other embodiments, as, for instance, where the accessories and their shafts are not supported on a plate which constitutes a section of the engine wall. The drawing of the accessories to the front end of the e g ne casing, it being assumed that this engine may be applied for the propulsion of an automobile having the usual radiator mounted at the rear end of the hood. in such a case, it will be evident that when the hood is *aised all of the accessories will be exposed at a very accessible place. Furth r, in the preferred construction, illustrated, the supporting plate for all of the accessories and their shafts is shown a detachable section of the front wall the engine casing.

in the drawing the front engine wall a has journaled therein the crank shaft 7) which extends forwardly to permit engage ment of suitable ratchet teeth Z)" thereon with a handle, as for initial cranking. This front wall is formed with two openings 2 adapted to be closed by a plate c which may be bolted to the front wall of the casing, as by bolts passing through holes 0'' therein. This plate carries a housing formed of two sections 0 0 which may be secured together by means of a. series of bolts 0 passing through the proximate faces of the sections at suitable points along the line of contact. lhe crank shaft 6 extends through the casing thus formed on the plate 0 and has keyed thereon within this casing a bevel gear (5 from which the various accessories of the engine are to be driven. Journaled in the upper wall of the casing is a vertical shaft 6, the bearings e of which may be clamped between the contacting edges of the sections 0 0 of the casing at this point. This vertical shaft may carry the water pump indicated generally at f and extends upwardto drive the overhead cam shafts (not illustrated). This shaft 6 has at its lower end a driving bevel pinion e in mesh with the bevel gear (5. Extending outwardly from one side of the casing formed by the sections 0 0 is a shaft 9 which drives the magneto, indicated will be obvious.

' shaft and the driven unit is eliminated.

generally at g. This magneto may be supported on a bracket h clamped or otherwise carried by the sections 0 c of the casing. The shaft 9 of the magneto is preferably inclined downwardly a little. On the inner end of the shaft is keyed a bevel pinion 9 which meshes with the bevel gear d. At the opposite side of the casing formed by the sections 0 c is journaled another shaft 5 which may drive a generator 6 supported on a bracket is clamped or otherwise carried by the sections 0 a This shaft a may be driven by a bevel pinion '5 disposed within the casing and in mesh with the bevel gear 03. -Extending downwardly in the casing formed by the sections 0 0 still. another shaft 1 which may carry at its upper end a bevel pinion Z to mesh with the bevel gear 03, and at its lower end an oil pump Z disposedbelow the level of the oil which may extend continuously from within the crank case through the opening a in the wall thereof into the lower portion of the housing formed by th ections 0 0 In the section 0 of the Iou'sing may be formed an opening 0 to receive an oil strainer m and this filler opening may be normally closed by a removable cover plate a, as is usual. A

The advantages in construction and useof the mounting described for the accessories These accessories are all brought into close proximity with each other so that access may conveniently be had thereto by a workman for inspection or repairs. Intermediate shafting between the cltlgk removal of the section 0 of the housing all of the shafts and their driving pinions are exposed to view for removal or adjustment. Further by removing the plate 0 all of the units may be taken from the engine without disturbing their relative positions in their bearings.

The invention, as stated hereinbefore, is not limited to the precise number or form of accessories so mounted, nor to the provision of a supporting plate therefor which constitutesa section of the engine wall.

The scope of the invention will appear from the appended claims.
